Description

Wood-plastic plate with fixing part
Technical Field
The present invention is in the field of general use forms or formwork members.
Background
At present, building templates are an important tool for concrete structure engineering construction, and outside the country, builders and contractors pay great attention to the templates, because the cost of the templates and the cost of using the templates account for 50% -60% of the cost of the whole concrete structure engineering, building template technology in industrially developed countries is continuously developed and applied with high-performance, energy-saving and environment-friendly template materials, and is reality and trend of international building template industry development. The templates used in the building industry at present are mostly ordinary plywood, but only can be turned for 3-5 times, and the service life is short. The metal templates, although long in life, are expensive and cumbersome to operate. The wood-plastic composite template is difficult to popularize and use in the field of building construction due to the fatal defect of low impact strength and bending modulus. In the prior art, when building formwork erection is carried out, a building formwork is required to be adopted for supporting, a molded surface is formed, concrete is supported by the formwork for a short time, and after the concrete is solidified, the formwork can be removed; the template can be repeatedly utilized; the traditional building template mainly comprises two types of wood templates and steel templates, wherein the wood templates are made of wood materials, can be made of solid wood boards, and can also be directly used as templates, one type of wood templates and wood multilayer composite boards can be cut, the use is convenient, the steel templates are made of steel materials, the single steel templates are generally required to be connected one by fasteners to form a whole when being erected due to small area, the templates have the defects that the wood templates and the steel templates are not waterproof, and the wood templates are easy to deform under the soaking of water; the steel mould is easy to rust, and has the advantages of heavy weight, inconvenient assembly and high cost.
The patent document with the authorized bulletin number of CN104775610B discloses a wood-plastic building template, which comprises an A plastic film, A glass fiber cloth, B plastic film and a group of composite powder layers, wherein the A plastic film, the A glass fiber cloth, the B glass fiber cloth and the B plastic film are respectively overlapped from bottom to top in sequence to form the wood-plastic building template, and the composite powder layers are respectively clamped among the A plastic film, the A glass fiber cloth, the B glass fiber cloth and the B plastic film. The scheme is made of waste materials, and solves the problem of high cost in the prior art. However, the layers are connected by using industrial glue, because the industrial glue contains volatile harmful substances such as formaldehyde, the harmful substances in the newly produced wood-plastic plate can be emitted from the tiny gaps on the wood-plastic plate, but the harmful substances sealed in the middle of the wood-plastic plate are completely and slowly emitted through the tiny gaps in the wood-plastic plate, so that a long time is required, and the long-term residue of the harmful substances can influence the normal use of a user on one hand, and can cause harm to the physical health of the user on the other hand.
Disclosure of Invention
The invention aims to provide a wood-plastic plate with a fixing part, which aims to solve the problem that harmful substances in the existing wood-plastic plate are emitted very slowly.
In order to achieve the aim, the basic scheme of the invention provides a wood-plastic board with a fixing part, which consists of an A plastic film, an A glass fiber cloth, a B plastic film and a plurality of composite powder layers, wherein the A plastic film, the A glass fiber cloth, the B glass fiber cloth and the B plastic film are respectively overlapped from bottom to top in sequence to form the wood-plastic board, the composite powder layers are respectively clamped between the A plastic film, the A glass fiber cloth, the B glass fiber cloth and the B plastic film, a hollow fixing part is arranged in the wood-plastic board, a plurality of through holes are formed in the fixing part, the fixing part is communicated to the surface of the wood-plastic board, the through holes are positioned on the contact surface of the A plastic film, the A glass fiber cloth, the B plastic film and the composite powder layers in a pair, the fixing part comprises a vent pipe and a plurality of hollow rods, the vent pipe is communicated with the hollow rods, and the hollow rods are arranged in an angle.
The principle of the basic scheme is as follows: all layers (hereinafter, all layers refer to an A plastic film, an A glass fiber cloth, a B plastic film and a composite powder layer) in the product are bonded by using industrial glue, a fixing part in the product is positioned in a wood-plastic plate, and harmful gas emitted by the industrial glue for bonding all layers enters the hollow fixing part from a through hole positioned at a contact surface of the layers. Because the fixing part is communicated with the surface of the wood-plastic plate, harmful substances are emitted out of the wood-plastic plate from the fixing part.
Because the breather pipe is arranged at an angle with the hollow pipe, the cross section area of the fixed part is changed along the axial direction of the breather pipe by the hollow pipe, and all layers in the product are respectively integrated, the layers can be blocked by the parts with larger cross sections of the fixed part when being separated, so that the layers are required to be separated, the resistance caused by the hollow pipe must be overcome, and the layers are prevented from being separated during the use.
The beneficial effect of this basic scheme lies in: 1. in the product, industrial glue is arranged on each layer of contact surface, and the through holes are positioned on each layer of contact surface, so that harmful substances emitted by the industrial glue can enter the hollow rod or the vent pipe through the through holes and can be rapidly discharged out of the wood-plastic plate through the vent pipe. Therefore, the product solves the problem of slow emission of harmful substances in the prior art.
2. The breather pipe and the hollow pipe in the product are arranged at an angle, so that the cross section area of the fixing part is changed, the resistance is increased when each layer is separated, and each layer is prevented from being separated during use. In addition, the vent pipe is arranged at an angle with the hollow pipe, so that the hollow rod extends to the side face of the vent pipe, and is parallel to the vent pipe relative to the hollow rod, namely, the side wall of the vent pipe is connected with the side wall line of the hollow rod, so that the contact area between the fixing part and the industrial glue is increased, and through holes can be formed in the increased area, namely, the number of the through holes is increased. More harmful gas can enter the hollow rod from the increased through holes and be discharged from the vent pipe, so that the discharging speed of the harmful substances is increased.
3. The product contains integrated glass fiber cloth, so that the product has the strength of glass fibers, and the strength of the product is enhanced.
The scheme is a basic scheme, and an optimization scheme I based on the basic scheme: the hollow rods comprise a first hollow rod and a second hollow rod, the first hollow rod and the second hollow rod are respectively positioned at two ends of the vent pipe, and the first hollow rod and the second hollow rod face towards the middle of the wood-plastic plate respectively. The first hollow rod and the second hollow rod which are respectively positioned at the two ends face the middle part of the wood-plastic plate respectively, so that the first hollow rod and the second hollow rod respectively form a barb shape with the vent pipe, the cross section area of the fixing part suddenly increases from the barb shape to the two ends, the separation of layers is more difficult due to the barb-shaped hollow rod and the vent pipe, and the separation of the layers is further prevented.
Optimization scheme II based on basic scheme: the composite powder layer is made of waste wood-plastic plates. The waste wood-plastic plate is reused, so that the cost is saved.
Optimization scheme III based on basic scheme: the number of the fixing parts is 4, and the fixing parts are respectively positioned at four corners of the wood-plastic plate. The layers are separated, typically starting with four corners, and then gradually increasing in separation speed. The fixing pieces positioned at the 4 corners of the fixing piece fix the four corners of the product and prevent the product from being separated from the four corners, thereby preventing the layers of the product from being separated quickly.
An optimization scheme IV based on the basic scheme I of the optimization scheme: the first hollow rod and the second hollow rod are respectively perpendicular to the vent pipe. The vertical hollow bar maximizes the cross-sectional area of the securing element, further increasing the resistance experienced by the layers as they separate, thereby further preventing separation of the product.
Optimization scheme five based on optimization scheme four: the hollow rods are distributed on the contact surfaces of the plastic film A, the glass fiber cloth B, the plastic film B and the composite powder layer which are in contact with each other in pairs. The hollow rods are distributed on the contact surfaces of all layers, so that the contact area of the hollow rods and the contact surfaces of all layers is larger, the positions where through holes are formed are more, and the more the through holes of the contact surfaces of all layers are, the faster the harmful substances are discharged, so that the harmful substances are further accelerated to be discharged from the product.
